Something fairly simple I would imagine...
This may have already been brought up - but perhaps a 'reminder' as such is needed?
Can we have the capacity of ambulance stations extended so that they can contain more vehicle bays? Something like a limit of 20 or perhaps even 25 would be more suitable I think. This will help those who base their service off of real life and wish to have rather large stations!
Could the hospital capacity also be brought up, to at least say 50? 30 seems a bit small for many city hospitals...
